Abstract
To permit at least partial disassembly of a drive motor (2) from a coupled pump system (3) to provide high hydraulic pressure, and separate portability of the motor element and the pump element, a cart, with wheels (4), is provided with a horizontally transversely extending mounting plate (28) on which the motor (22) can seat, with its motor shaft (27) extending vertically. The pump unit (3), which can be formed of two or more high-pressure hydraulic pumps and include a cooling water circulating pump (14), has a vertically extending pump shaft (56). The motor shaft and the pump shaft extend through the mounting plate, and a transmission, preferably a belt transmission, is located below the mounting plate. The belt transmission may include a drive pulley which is hollow in the middle, and formed with an internal gear (33) which engages an external, axially curved gear (14') on the motor drive shaft, to form a separable coupling. The motor can be lifted off the cart, and transported separately.
